HOSE-CLAMP.

Specification of Letters Patent.

Patented May 29, 1906.

Application filed $eptember 26, 1905. Serial No. 280,216.

To all whom it may concern:

Be it known that I, JOSEPH W. ADAMS, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful Hose-Clamp, of which the following is a specification.

This invention relates to hose-clamps, and

has for an object to provide a device of the class embodying new and improved features of durability, convenience, utility, and efliciency. A further object of the invention is to provide a clamp which may be applied to and removed from a hose without the use of tools of any kind.

A further object of the invention is to provide a clamp which when clamped upon a hose is held in such clamped position by the resiliency of the hose.

With these and other objects in view the present invention consists in the combination and arrangement of parts as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in form, proportion, size, and minor details may be made without departing from the spirit or sacrificing any of the advantages of this invention.

In the drawings, Figure 1 is a perspective view of the improved hose-clamp clamped upon a hose and part of a coupling. Fig. 2 is a perspective view of the clamp upon a hose and unclamped and ready for removal. Fig. 3 is a view of the clamp in side elevation, showing the curvature of the handle. Fig. 4 is a perspective view of the flexible band and associated parts. Fig. 5 is a view in front elevation of a modified form of the clamp applied.

Like characters of reference indicate corresponding parts in all of the figures of the drawings.

In its preferred embodiment the improved hose-clamp forming the subject-matter of this application comprises a flexible band 10, having studs 11 11 radially outstanding therefrom adjacent their free ends. The studs 11 11 are secured to the band in any approved manner, as by riveting, and are provided at their extremities with heads 12 12. To bridge the space between the free ends of the band, a guard-section 13 is provided and arranged in any approved manner for circumferential adjustment, as by the lips 14, formed over the opposite edges of the band, so that the band so provided with its adjustable section may entirely encircle a hose, as 15, to clamp it upon any desired device, as the coupling member 16.

To clamp the band, a handle member 17, being broad at one end, as 18, and with the broad end curved from about the point indi cated at 19. The handle is provided at its broad end with the eccentric cam-slots 2O 21, each enlarged at one end, as at 22 23, to pass over the heads 12 12 and engage the studs 11 11. Opposite the handle the broadened end is provided with a point 24, which when the device is locked contacts with the hose and being past the middle is retained by the convexity and resiliency of the hose. The end of the handle opposite the point 24 is beveled, as 25, for the purpose of offering less surface upon which objects may catch to disengage the handle.

In the form shown in Fig. 5, finger 26 is provided at the end of the handle to contact with the side of the hose and prevent backward movement. In Fig. 5 the eccentric slots are beveled along their outer edges, as at 27 27, whereby the studs 11-11 may be made shorter, and thereby less liable to breakage.

With the parts assembled as shown in Fig. 2 the hose may be readily removed from the coupling .and the band from the hose, if desired. The coupling may be any form of tubular shank upon which it is desirable to attach a hose, but, as shown and primarily intended, the coupling forms the outer extremity of a hydrant and will remain thereon,

the hose and clamp being disconnected and removed from the coupling when it is desired to remove the hose for reeling or other purposes. To couple the hose, the band is placed upon the hose and the hose upon the coupling. The handle is then applied by passing the openings 22 23 over the heads 12 12 and moving the handle in the direction of the arrow. It will be readily understood that the eccentric slots approach nearest to each other on the line, as A B, perpendicular to a line, as C D, which passes through the centers of the openings 22 23 and that when IO 5 the studs 11 11 advance beyond such line A B they tend to separate, thereby preventing a backward movement of handle except under the influence of force.

In applying the form shown in Fig. 5 the no hose is bent backward to permit the finger 26 to pass thereover, and when the hose is released it will spring up in the path of and prevent a return movement of the handle.

It will be apparent that the clamp may be operated without the use of tools and that the hose may be quickly and conveniently attached to and detached from the hydrant or other pipe, and when so removed the band may be clamped upon the hose for storage in the same manner as though upon a coupling.

Having thus described the invention, what is claimed is 1. A hose-clamp comprising a hose-embracing band provided with terminal studs, and a handle member provided with oppositely-directed cam-slots engaging the studs and so curved that both ends contact with the hose.

2. A hose-clamp comprising a hose-embracing band, provided with terminal studs, a guard member slidably mounted thereon and bridging the interval between the terminals and a handle member provided with oppositely-directed cam-slots and so curved that both ends contact with the hose.

3.'A hose-clamp embodying a flexible band carrying rigid studs, a handle engaging the studs to clamp the band upon the hose and means whereby the handle is held from a return movement of the hose.

4. A hose-clamp embodying aflexible band, studs radially outstanding from the band adjacent the free ends, a handle engagingthe studs to clamp the band upon the hose and means whereby the handle is held from a return movement by the hose.

5. A hose-clamp embodying a flexible band, studs radially outstanding from the band adjacent the free ends, a handle having camslots engaging the studs to clamp the band upon the hose and means whereby the handle is held from a return movement by the hose.

6. A hose-clamp embodying a flexible band, headed studs radially outstanding from the band adjacent the free ends, a handle having cam-slots engaging the studs to clamp the band upon the hose, and means whereby the handle is held from a return movement by the hose.

7. A hose-clamp embodying a flexible band provided with a circumferentially-adjustable guard-section, a handle for clamping the band up on the hose and relative to the guardsection and means whereby the handle is held from a return movement by the hose.

8. A hose-clamp embodying a flexible band provided with a circumferentially-adjustable guard-section, and headed studs radially outstanding from the band adjacent the ends connected with the guard-section, a handle having eccentric cam-slots engaging the studs to clamp band upon the hose and means whereby the handle is held from a return movement by the hose.

9. A hose-clamp comprising a flat band and a lever having oppositely-directed camslots detachably engaging the ends of the band, said ends being incapable of independent lateral movement.

10. A hose-clamp comprising a flat band having studs upon its end portions and a lever having oppositely-directed cam-slots constituting guides for the studs, the ends of said band being incapable of independent lateral movement.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
